flock of Band-tailed Pigeons flushing at the approach of a Cooper's Hawk, which calls once after 0:07.5, and with the alarm of Mexican Jay as well, which had just before the recording signaled some concern; not all the pigeons went very far, so some growling calls toward end as pigeons re-established preferrerd perches; (Band-tailed Pigeons are too large for a Cooper's Hawk to take easily, but they do get out of the way)

the song at start is of the type that ends with many rougher, softer notes; then several widely space periods with many growling interaction calls related to space issues among birds in a flock in a tree

multiple birds singing, including some good sections like 2:10 and 3:45, from cypress and sycamore trees, from a flock of dozens, but a tough background of wind and other birds; flock flushed at 5:02 by Cooper's Hawk with loud clapping of wings just after Mexican Jays started alarm; interval altered at 1:55 and 2:25; some growling interaction calls after 1:58
